Hi,
I am creating XML with a CDATA section and until recently I was using XML.CDATASection to do this, but then
changed it to XMLNSC.CDataField when I needed to output namespace xml in this field and got an error using XML.
However the XMLNSC.CDATASection seems to cause the generation of a NULL tag which does not validate,
neither in XMLSpy nor in MQInput node on trying to read the message written to a queue.

During testing I created both CDATA sections using both XMLNSC and XML e.g.:

SET excRef.MessageDetails.MessageDomain = 'XMLNSC';
CREATE LASTCHILD OF OutputLocalEnvironment.InputMsg DOMAIN('XML') PARSE(ASBITSTREAM(InputRoot.XMLNSC));
SET excRef.MessageDetails.MessageData[1].(XMLNSC.CDataField) = CAST(ASBITSTREAM(OutputLocalEnvironment.InputMsg.XML) AS CHAR CCSID 437);
SET excRef.MessageDetails.MessageData[2].(XML.CDataSection) = CAST(ASBITSTREAM(OutputLocalEnvironment.InputMsg.XML) AS CHAR CCSID 437);

Traces from both sides on the MQOutput node are identical and show:
(0x01000000):MessageDetails = (
(0x03000000):MessageDomain = 'XMLNSC'
(0x01000000):MessageData = (
(0x03000001): = '<?xml version="1.0" encoding="UTF-8"?><methodCall>...</methodCall>'
)
(0x01000000):MessageData = (
(0x02000001): = '<?xml version="1.0" encoding="UTF-8"?><methodCall>...</methodCall>'

This gave rise to the output (as viewed in RFHUtil):
<MessageDetails>
<MessageDomain>XMLNSC</MessageDomain>
<MessageData>
<><![CDATA[<?xml version="1.0" encoding="UTF-8"?><methodCall>...</methodCall>]]></>
</MessageData>
<MessageData><![CDATA[<?xml version="1.0" encoding="UTF-8"?><methodCall>...</methodCall>]]></MessageData>
</MessageDetails>

The extra "<>" and "</>" on the XMLNSC.CDataField are not valid xml. It looks like an extra outer tag is being
generated with null tag name!

Has anyone seen this before and found a solution??
